Abstract
Способ получения 1,2-дихлорэтана с использованием этана в качестве исходного соединения, в соответствии с которым: а) поток этана подвергают каталитическому оксидегидрированию с образованием смеси газов, содержащей этилен, не прореагировавший этан, воду и вторичные компоненты; b) указанную смесь газов необязательно промывают и сушат и таким образом получают смесь сухих газов; с) после необязательной дополнительной стадии очистки указанную смесь сухих газов подвергают абсорбции А1, которая включает разделение указанной смеси газов на фракцию, обогащенную соединениями, более легкими, чем этилен, и содержащую некоторое количество этилена (фракция А), и на фракцию F1; d) фракцию А направляют в реактор хлорирования, в котором большая часть этилена, присутствующего во фракции А, превращается в 1,2-дихлорэтан, и полученный 1,2-дихлорэтан необязательно отделяется от потока продуктов, который выводится из реактора хлорирования; е) необязательно поток продуктов, который выводится из реактора хлорирования и из которого необязательно экстрагирован 1,2-дихлорэтан, подвергают абсорбции А2, которая включает разделение указанного потока на фракцию, обогащенную этаном F2, которую затем возвращают в фракцию F1, и на фракцию, обогащенную соединениями, более легкими, чем этан F2' ; f) фракцию F1, которая необязательно содержит фракцию F2, выделенную на стадии е) абсорбции А2, подвергают десорбции D, которая включает разделение фракции F1 на фракцию, обогащенную этиленом (фракция В), и на фракцию F3, необязательно содержащую 1,2-дихлорэтан, образовавшийся в реакторе хлорирования, который затем извлекают, если он не был извлечен ранее, возвращаемую обратно по меньшей мере на одну из стадийA method for producing 1,2-dichloroethane using ethane as the starting compound, in accordance with which: a) the ethane stream is subjected to catalytic oxydehydrogenation to form a mixture of gases containing ethylene, unreacted ethane, water and secondary components; b) said gas mixture is optionally washed and dried, and thus a dry gas mixture is obtained; c) after an optional additional purification step, said dry gas mixture is subjected to A1 absorption, which comprises separating said gas mixture into a fraction enriched in compounds lighter than ethylene and containing a certain amount of ethylene (fraction A), and into fraction F1; d) fraction A is sent to a chlorination reactor, in which most of the ethylene present in fraction A is converted to 1,2-dichloroethane and the resulting 1,2-dichloroethane is optionally separated from the product stream that is discharged from the chlorination reactor; e) optionally, a product stream that is discharged from the chlorination reactor and from which 1,2-dichloroethane is optionally extracted is subjected to A2 absorption, which comprises separating said stream into a fraction enriched in ethane F2, which is then returned to fraction F1, and to a fraction enriched in compounds lighter than ethane F2 '; f) fraction F1, which optionally contains fraction F2, extracted in step A2) absorption A2, is subjected to desorption D, which includes the separation of fraction F1 into a fraction enriched in ethylene (fraction B) and fraction F3, optionally containing 1,2-dichloroethane formed in the chlorination reactor, which is then recovered, if it has not been recovered before, is returned back to at least one of the stages
